A riding type battery car was built for transporting in horticultural greenhouses and in various agricultural facilities. The mechanism and performance of this car were summarized as follows:
1. The car was equipped with a D. C. motor as the prime mover. The voltage and output of the motor was 12V and 250W respectively. The car had four speeds forward and two speeds backward, the travel speeds varied from 0.15 to 0.7m/s.
2. Maximum input of the motor was about 180W on the earth road when loaded 126kg (maximum load) at the speed of 0.5m/s.
3. The overall efficiency on input basis of the car was 44% at maximum on the earth road.
4. Continuous operation hours of the car were about 3 hours when loaded 21kg and travel speed was the top, and the total running distance was 7, 000m.
5. As a result of simulation of harvesting and transporting with the model planting device, the work efficiency was higher for the customary working with the hand-basket than for the car, but the accuracy of picking for the car was better than for the hand-basket.
